Excel/CSV 导入导出库，支持大文件，样式设置

前言

• 项目上使用过maatwebsite/Excel, mk-j/php_xlsxwriter, box/spout这三个库，简单说下使用体验
• maatwebsite/Excel 优点功能非常强大，不足的是占用内存太多，对于导出大文件无法满足需求
• mk-j/php_xlsxwriter 优点支持大文件写入，常规样式设置，不足的是仅支持excel导出，不支持导入，也不支持csv的导入/导出
• box/spout 优点是支持大文件，支持excel/csv导入/导出，不足的是不支持单元格合并

环境要求

• PHP version 7.1 or higher
• PHP extension php_zip enabled
• PHP extension php_xmlreader enabledR

##安装

• composer require rocky114/spreadsheet
• https://github.com/rocky114/spreadsheet

导出

include "./vendor/autoload.php";

$writer = \Rocky114\Excel\Writer\WriterFactory::createXLSXWriter();
$writer->setTempFolder('.');

$writer->addNewSheet('sheet1');

$type = ['A' => 'string', 'B' => '#,##0'];
$writer->addHeader(['name', 'id'], $type)
->addRow(['xinzhu', 1234565])>addRow(['rocky', 21])->save();

导入

include "./vendor/autoload.php";

$reader = \Rocky114\Spreadsheet\ReaderFactory::createReaderFromFile('./test.xlsx');

$data = [];
foreach ($reader->getSheetIterator() as $sheet) {
     foreach ($sheet->getRowIterator() as $row) { 
        $data[] = $row; 
     }
}

// or
$data = $reader->getSheet()->load();
